UNITEn STATES PATENT IEFICIE IMPROVEMENT in eLorH-cu-rrme MACHINES.

Specification forming part of Letters Patent No. 130,910, dated August27, 1872.

We, ISAAC FENNO and PATRICK Howie, both of Boston, in the county ofSuffolk and State of Massachusetts, have jointly invented certain newand useful Improvements on Machines for Cutting Cloth or other textileand fibrous materials, of which the following is a specification:

Nature and Objects of the Intention.

The nature Of our invention relates to im-l provements on cuttin-machines for cloth, Snc., consisting in the `employment of areciprocating cutter, made to move up and down in suitable bearingsattached to a jointed arm. The cutter is operated by means of belts andgea ings, or their equivalents, in a manner as will -now be shown anddescribed.

On the drawing, Figure l is a ground plan. Fig. 2 is a centrallongitudinal section over the line A B taken on Fig. 1. Fig. 3 is anenlarged end view, seen from a' on Fig. 2.

Similar letters refer .to similar parts wherever they Occur on thedrawing.

This, our invention, is an improvement on the application liledJoy us inthe United States Patent Office April 15, 1872; and it differs mainlyfrom that application in this wise, that we now employ a reciprocatingcutter instead of a revolving disk cutter, as we formerly employed. Thereciprocating cutter is Operated in the end of a jointed arm, as willnow be shown. l

The horizontal shaft a is set in motion by a bevel-gear, b, attached tothe said shaft a.. The bevel-gear b gears into a similar bevelgear, c,attached to the upright shaft d, as 0n the upper end Of the shaft d iskeyed a pulley, e, that is set in motion by means of a belt, f, leadingfrom the pulley g. The pulley g is made in one piece with or attached tothe pulley h, and both pulleys g h are made to revolve loosely aroundthe upper end of the hinge-pin t. The pulley h is s'et in motion bymeans of the belt k, leading from the pulley l, keyed to the uprightshaft m. The shaft m revolves in the hub a, being the upper part of thestandard o. The standard o is held firmly to the operating-table p bymeans of screws, bolts, or otherwise. On the lower end of the shaft misattached a bevelgear, q, that gears into a similar bevel-gear, T,attached tothe driving-shaft s, supported in a suitable bearing in thestandard o. On the shaft s is also keyed or attached the driving-pulleyt, to which the power is applied in any of the ordinary ways. The arm uis provided with a perforated hub, fv, that its over the hub n, andaround which it is made to swing easily. The arm u is hinged to the armw by means of the hinge-pin t', as shown on the drawing. The extreme endof the arm w is made as a sleeve, y, that constitutes a bearing for theupright shaft d. Over the lower end of the sleeve y is tted the cylinderz, provided with a handle, l, by means-of which the whole may be guidedin any direction over the material that is to be cut. The cylinder z iskept in place byfmeans of the small setscrew 2, that projects in agroove turned on the sleeve y, as shown, by which arrangement thecylinder z can be swung around the sleeve y without being detached fromthe same. On the forward end of the shaft a is attached a crank or itsequivalent, 3, provided with a crank-pin, 4, fitted with the block 5,shown in Figs. 2 and 3. The block 5 is made to play in the groove 6 thatis cut in the guide-piece 7. The guide-piece 7 is made to move up anddown in guides 8 8 attached to the cylinder z. On the under side of theguide-piece 7 is secured the reciprocating cutter 9, that is made tomove up and down by means-of the parts, or their equivalents,hereinabove described. An adjustable foot-piece, 10, is attached to someconvenient place on the guides 8 8 Or the cylinder z, in such amannerthat it may be raised up Or adj usted according to the thicknessof the material that is to be cut. The cutter'9 may be pointed, asshown, and made sharp on both edges, so as tO cut in any direction inwhich it is moved.

Having thus fully described the nature, construction, and operation ofour invention, we wish to secure by Letters Patent, and claim 1ncombination with the jointed arms u w, the reciprocating cutter 9,operated by the moving parts or their equivalents, as and for thepurpose herein described.
